To all whom it may concern:

Be it known that l, SOMA KACSER, a citizen of Czechoslovakia, residing at Berlin, Germany, have invented certain new and useful Improvements in a Retort for the Distillation of Bituminous Materials (for which I have filed application in. Germany, July 3, 1920), of which the following is a specification.

- The present invention relates to a retort for the distillation of bituminous'materials,

such as; slate, rock asphalt, lignite, peat and the like, as well as other distillable mavte'rials allowing an excellent utilization of the employed heat, a higher yield of the highly valuable oilsand a greater charging capacity, being of simple construction, thus giving an easy accessibility to all parts of the apparatus. jamming, clogging, or caking of the material is prevented as the said material is continuously and thoroughly mixed and all particles brought into contact with the heated walls of the apparatus. The distilled gases are immediately conducted from the gasifying-zone into cooler surroundings, to'prevent secondary decomposition, to which especially the constituents of tar of a higher boiling point are subject, and which are very valuable as lubr cants. A very important feature is that only a thin, layer of material is accumulated on those zones where the most vigorous production of gases or vapours takes place, so that practically. no mechanical resistance 0pposes the escape of the before mentioned products. Further, the possibility of introducing steam at these zones for assisting the distillation and also for discharging the hot distillation residues is conducted in such a manner that a further ut lization of heat may result. The invention consists of an. open ended rotary cylinder arranged Within an outer casing and surrounding a stationary internal heating tube whereby the material is carried through the said rotary cylinder in such a manner that itv "will cover the aforesaid heating tube.

In the accompanying drawings M several constructions of the invention are illustrated. Fig. 1 is a side elevation partly in section illustrating one form of the improved retort.

Fig. 2 is a cross. section of Fig. l on the line w3 I Fig. 3 is a cross section through the rotary cylinder of an. alternative construction.

, Fig. 4 is a cross section through the rotary cylinder of a further modification.

Fig. 5 is a cross section through the rotary cylinder on a larger scale of a still further modification.

Fig. 6 is a longitudinal section of an arrangement of two retort units in a single outer casing.

Fig. 7 is a cross section centrally of Fig. 6. v

Fig. 8 is a cross section similar to Fig. 6

showing four retort units in a single outer casing.

Fig. 9 is a longitudinal cross section similar to Fig. 1 showing a tandem arrangement of two retort units.

Fig. 10 is a cross section of a double rotary cylinder.

The apparatus (Fig. 1) consists of a stationary outer casing B provided with a. heating tube A and a cylinder Cl open at both ends and rotatably mounted between the heating tube A and the outer casing B. The materials to be distilled are fed into the cylinder C Where they accumulate around the heating tube by means of a feeding device .V' hich prevents any escape of gases during the charging, the said fteding device V being arranged on one end plate of the outer casing B. l

By mounting the apparatus at an inclina tion or by means of suitably shaped blades D (Figs. 1 and 4:) Within the cylinder C the material will be lifted, mixed and oved in a direction towards the other end pl to of the casing B and may be discharged by means of a suitable and gast-ight discharging device W. At various places in the cylinder .0 instead of the blades D are shovels'or buckets E (Fig. 5 provided for taking upa part of the material and allowing it to trickle on the to part ofthe heating tube during the rotation of the cylinder C so that this part of the heating tube will be continuously covered with fresh and moving material, furthermore the plates F may be rigidly arranged above the heating tube .to secure an even spreading of the material on both sides of th heating iube, inns presure or veeuuin as the cylinder is net hervent n eecuimi. etien ef the Kaeteriau on nietieziiiy closed.

' possible eiiiciency,

solute possibility of regulation of the heating gases in accordance with the velocity of movement of the material as well as the possibility of direct steam supply at various zones, results in a practically complete utilization of the heat, as well'as in the highest ing tube, the durability of the. apparatus is not only increased, but also the thickness of the olates of which it is, composed may be muci less than in apparatus with external heating.

One form of construction of this invention consists in the arrangement of two or more. heating tubes one above the other, or above and side byside, as shown in the Figs. 6 -8. By this means the constructive ength of the apparatus is considerably shortened and a still more intensive utilization of the heat obtained, as the cooling outer surfaces are considerably reduced. The heating takes place from below upwards, the charging being made at the top andthe discharging at the bottom of the apparatus.

In Fig. 6 the material is brought from one rotary cylinder to the other one by means of a slide S. A further modification is illustrated in ,Fig. 10 in which the. rotating cylinder is made as a double cylinder, the outer cylinder is provided with the same devices, i. e., {as openings, guide blades, as the inner cylin er. The gas openings K of the inner cylinder are connected with the outer cylinder b means of the tubular connections T. barging takes place in the interspace where the ma terial is preheated and the lower volatile constituents gasified. The material is then brought into the inner cylinder by means of slides (not shown) where the further gasiiying is completed.

In apparatus of very great length it is necessary to divide the rotary cylinder in two. parts arranged in tandem fashion (Fig. 9) and to provide a support U for the heating tube, in thiscase the driving of the cylinders may be effected'froin one single shaft '11, and toothed wheels of and W.
